GEORGE J. SCHADE, OF SANDUSKY, OHIO.

To all whom it may concern:

Be it known that I, GEORGE J. SOHADE, a citizen of the United States ofAmerica, residing at Sandusky, in the county of Erie and State of Ohio,have invented certain new and useful Improvements in Metal Reinforcementfor Metal-Reinforeed-Concrete Columns, Posts, and the Like; and I herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

This invention relates to an improved metal reinforcement formetalreinforced concrete columns, posts and the like, and pertains moreespecially to a metal reinforcement for upwardly tapering posts or polesand for continuous columns extending through or into adjacent stories ofa buildmg.

My improved metal reinforcement comprises more especially twosubstantially vertically arranged metal rods mounted the one upon theupper end of the other.

The primary object of this invention is to provide simple and efficientmeans whereby the said rods are rigidly secured together.

Another object is to secure the said rods together by means comprising astrong metal clip which extends up and down the adjacent portion of therods and is looped or bent about and clamped to the said portions of therods and positively prevented from slipping downwardly.

Another object is to have the clip properly fit an upper rod which issmaller in cross section than the lower rod by the provision of. theclip with a lateral and inward ofiset over the upper end of the lowerrod so that the upper portion of the clip above the said offset and thelower portion of the clip below the said offset embrace the upper rodand lower rod respectively.

Another object is to most efficiently secure the clip and the rodstogether by providing means whereby the upper rod and the clip areclamped together at a plurality of vertically spaced points above thejoint between the rods, and means whereby the lower rod and the clip areclamped together at a plurality of vertically spaced points below thesaid joint.

With these objects in view, and to the end of realizing other advantageshereinafter appearing, this invention consists in certain features ofconstruction, and combinations Specification of Letters Patent.

Application filed March 5, 1909.

Patented Dec. 1a, 1999.

Serial No. 481,476.

' of parts, hereinafter described, pointed out in the claims, andillustrated in the accompanying drawings.

In the said drawings, Figure l is a side elevation of two substantiallyvertical metal rods arranged the one upon the upper end of the other andsecured together by means embodying my invention. Fig. 2 is a left handside elevation relative to Fig. 1. Figs. 3 and 4: are horizontalsections on lines 3-8, and t4;, respectively, Fig. 1, lookingdownwardly.

Referring to the drawings, A represents a substantially verticallyarranged metal rod.

B indicates a substantially vertically arranged metal rod which ismounted or rests upon the upper end of the rod A.

Both rods A and B are shown circular in cross section. The upper rod Bis smaller in cross section than the lower rod A and as shown arrangedcentrally of the upper end of the lower rod. The rods A and B form aportion of a metal-reinforcement for reinforcing concrete columns, postsand the like in metal-reinforced concrete construction. I A not uncommonway of using the metal reinforcement formed by the rods A and B inmetal-reinforced concrete construction is to have the lower rod A extendthrough one story of the building into the next upper story and employedin supporting the floor between the said stories, and to have the upperrod B extend through the upper of the said stories and instrumental insupporting the floor or roof at the top of the said upper story.

My invention consists essentially in the provision of means forinexpensively but very efficiently securing the rods A and B together,which means comprise a metal clip C which preferably consists of a steelplate which extends up and down the adjacent portions of the rods and islooped or bent, as at 5, about the said portions of the rods at one andthe same side of my improved metal reinforcement and has substantiallyparallel side portions 6 and 7 arranged at opposite sides respectivelyof the rods and projecting outwardly from opposite ends respectively ofthe loop or bend 5. The upper rod B obviously does not cover the entireupper end surface of the lower rod A but is arranged centrally of thesaid surface, as already indicated, and the plate or clip C is offsetlaterally and inwardly, as at 8, over the upper end of the lower rod andhas its upper portion and lower portion embracing the upper rod andlower rod respectively. That is the upper part and lower part of theloop or bend 5 fit and embrace the upper rod and lower rod respectively,and the offset 8 also materially strengthens the clip. The offset 8 ofthe clip cooperates with the upper end of the lower rod to preventdownward slipping of the clip, but the clip is preferably provided withlaterally and inwardly projecting lugs 10 which directly rest upon theupper end of the lower rod A and are spaced circumferentially of thelower end of the upper rod B and positively prevent downwarddisplacement of the clip. The upper rod B is clamped above the jointbetween the two rods against the inner side of the loop or bend 5 of theupper part of the clip preferably by two vertically spaced wedges 20which are supported from the said part of the clip and respectivelyextend substantially horizontally through two holes or perforations 12and 13 formed in the side portions 6 and 7 respectively of the said partof the clip, which holes or perforations have their side walls whichface laterally in the direction of the said loop or bend engaged by thesaid wedges, and the said holes or perforations extend far enough in thedirection of the said loop or bend to accommodate the driving of thewedges tightly between the said walls and the upper rod and therebyeiiiciently secure the clip to the said rod. The lower rod A is clampedbelow the joint between two rods against the inner side of the loop orbend of the upper part of the clip preferably by two Vertically spacedwedges l/V which are supported from the said part of the clip andrespectively extend horizontally through two holes or perforations 14:and 15 formed in the side portions 6 and 7 of the said part of the clip,which holes or perforations have their side walls which face laterallyin the direction of the said loop or bend engaged by the said wedges,and the said holes or perforations extend far enough in the saiddirection to accommodate the driving of the wedges tightly between thesaid walls and the lower rod and thereby effectively secure the clip tothe said rod.
